PAPER VESSEL.

SPECIFICATION forming part of Letters Patent No. 635,350, dated October 24, 1899.

Application filed April 27, 1899.

at Chicago, county of Cook, and State of Illinois, have invented a certain new and useful Improvement in Paper Vessels, of which thefollowingis a description, reference being had to the accompanying drawings, forming part of this specification.

My present invention relates to an improvement upon the paper pail shown and described in my pending application, Serial No. 697,090, filed November 21, 1898; and it consists in the provision of novel means for retaining the two inner cover-flaps in their normal open position and preventing them from being bent outward or backward beyond such position, all as hereinafter more fully described, and particularly pointed outin the claims.

In the accompanying drawings, Figure -1 represents the blank of my improved pail properly cut and scored or creased for its intended purpose; Fig. 2, a vertical cross-sec- 'tion of the completed pail in open position,

and Fig. 3 a corresponding View with the two inner cover-flaps bent downward to closed position.

Thesame letters of reference are used to indicate identical parts in the several views. The blank shown in Fig. 1 is composed of the usualbottom portion A, side walls B CD E,

and the corner-flaps F G H I. The side walls B D are separately provided with the extensions J L, constituting the inner cover-flaps, while the side walls 0 E are provided with the ex tensions K M, constituting the upper or outer cover-flaps, Each of the inner coverflaps J L is provided upon its opposite edges with an extension 0, each of which extensions O is in the present instance formed into a hook 0, adapted .to cooperate with the extensions K M of the side walls 0 E, constituting the two upper or outer cover-flaps, in the manner hereinafter described. Each of the latter is creased or scored transversely along the line a to adapt the extension to be folded upon itself, as in Figs. 2 and 3, the portions K M beyond the lines a being adapted to lie. against the portions inside those lines and to also overlap the side walls Serial No. 714,755. (No modelfi O E and cover the clenched inner ends of the wire bail N, as in my prior pail, upon which the present improvement'is based. This latter feature (the covering of the ends of the wire bail) is not, however, essential to my present improvement. The portions K M of the cover-flaps K M are each provided upon their opposite sides with hooks or shoulders N, adapted to cooperate with the hooks 0 upon the extensions 0 of the cover-flaps J L in the manner indicated in Fig. 2.

The blank shown in Fig. 1 is folded into pail form in the usual manner, the corner folds being overlapped upon the outer surfaces of the side walls 0. E and secured thereto by means of the bailN, whose ends are passed through such overlapped corner folds and through the side walls 0 E and clenched upon the inner surfaces of the latter, and the extensions K M being bent over upon the flaps K M and secured thereto by the usual or any suitable fastening devices P. When this is done, the extensions 0 of the cover-flaps J L will under the usual manner of folding the pail stand outside the cover-flaps K M, projecting from the upper edges of the side walls C E. To get them inside of such extensions and engage the hooks O' with the shoulders N, as in Fig. 2, the cover-flaps J L will be bent outward and backward sufficiently to permit the extensions 0 to be brought inside the extensions K M, and upon then bending the flaps J L inward and downward toward each other their extensions 0 will pass downward over the inner surfaces of the parts K M, their tendency to spring outward serving to press them against the surfaces of said parts K M, and when the hooks 0 clear the edges of the parts K M said hooks will naturally spring outward and rest directly against the inner surfaces of the side walls 0 E.- Upon then releasing the cover-flaps J L and permitting them to spring upward and outward to normal position the hooks 0 will pass beneath the parts K M and become engaged with the shoulders N, as shown in Fig. 2. The parts K M do not naturally fit so snugly against the inner surfaces of the side walls 0 E (especially where their lower ends are held slightly away from such surfaces by the I ready admission of the hooks O between the parts K M and the surfaces against which they rest, and while considerable description is required for the foregoing explanation in detail of the exact manner in which the extensions O are brought inside of the side walls C E and their extensions and the hooks O, engaged with the shoulders N, it will be understood that the actual operation is very brief and simple, it simply being necessary to grasp the opposite cover-flaps J L with the two hands and press their extensions 0 inward with the thumbs and fingers as the flaps J L are pulled slightly outward and then press the flaps J Linward and downward the proper distance and release them, the hooks O in most cases automatically engaging the shoulders N as the flaps J L spring upward and outward to normal position.

So far as I am aware no paper pail has heretofore been provided with anything similar to the hooked extensions 0 O of the cover-flaps J L, adapted to cooperate in any way with vertical extensions of the side walls 0 E for the purpose described, and my invention therefore c ontemplates in its broader scope such variations from the exact construction which I have illustrated and described as permit the essential functions and mode of operation of the parts to be retained. For instance, by the way of mere illustration, the hooks 0' may be made to engage slits or openings in the parts K M or even in the parts K M instead of engaging the shoulders N, formed upon the edges of the parts K M; but the actual construction which I employ facilitates the automatic engagement of the hooks O with the parts K M', and is therefore preferable, although the suggested arrangement is clearly within the contemplation of my invention.

Aside from their hooks O the extensions 0 of the cover-flaps J L serve the same purpose in my present pail as in my prior one heretofore referred to, beingadapted to abut at their lower edges against the side walls B D when the flaps J L are bent down to horizontal position, as in Fig. 3, and brace and support the cover of the pail when closed.

Having thus described my invention, 1 claim 1. The herein-described paper vessel in which the two cover-flaps formed by the vertical extensions of two of the opposing side walls of the vessel are each provided with means adapted to cooperate with separate and independent means provided upon the vertical extensions of the other two side walls of thevessel for the purpose of preventing said cover-fiaps from being bent outward from normal open position, substantially as described.

2. The herein-described paper vessel having its coverflaps J L provided with the hooked extensions 0 0 adapted to cooperate with the vertical extensions of the side walls C E for the purpose of retaining the flaps J L in normal open position,substantially as described.

3. The herein-described paper vessel in which the side walls 0 E are provided with the vertical extensions K M having the portions K M folded upon them and resting against the inner surfaces of the pail, and in which the cover-flaps J L are provided with the hooked extensions 0 0 adapted to 006perate with the parts K M for the purpose of preventing outward movement of the flaps J L from their normal open position, substantially as described.

4. The herein-described paper pail having its side walls 0 E provided with the vertical extensions K'K and M M, the parts K M being folded inward upon the parts K M and provided with the shoulders N, and the side walls 13 D having the vertical extensions J L provided with the hooked extensions 0 0 adapted to cooperate with the shoulders N in the manner and for the purpose described.
